Frequently Asked Questions


  • How to choose a miniature refrigerated compressor?
  • How to choose a compact cooling system or module?


Do you have a small cooling unit that could cool a box approximately 100L?

It depends on the target temperature, there are two options for space cooling.

  1. The direct expansion system is a great choice to cool this space volume lower than 0℃. Customers can attach the evaporator according to the project requirements.
  2. Micro DC aircon is an air cooling system able to cool 45-100 cubic feet(1000L-2000L) to 16 ℃. The refrigerant is fully charged.
What's system does the micro DC aircon used?

RIGID micro DC aircon is be used in a variety fields for the compact dimension. Such as EV battery, Drone Docking Station, Small Van cabin, Camping, Vertical Farming, Trailer, City EV, Telecom Cabinet etc.

How do I determine the appropriate cooling capacity that required ?

The cooling capacity of liqud cooling unit will be related to the amount of water, target temperature, and time. For the air cooling system, the room size and how quick it need to cool is direct effect the cooling capacity.

How many degrees can the temperature decrease compared to the outside one?

Normally 10℃-15℃. The performance will be better if it has good insulation and adequate ventilation of the exhaust air.

Which kind small chiller is suitable for body cooling?

Liquid Cooling System is the most active body cooling approach. Using a circulating chilled liquid as the cooling medium to cool body, provide whole days cool.
